A new rollup tool now exists for flattening out the headers in a way that works better for our purposes than cpp. A lot of the API clutter has been removed. APIs that aren't a sure thing in terms of general recommendation are now marked internal. There's now a smoke test for the amalgamation archive and gigantic header file. So we can now guarantee you can use this project on the easiest difficulty setting without the gigantic repository. A website is being created, which is currently a work in progress: https://justine.storage.googleapis.com/cosmopolitan/index.htmlmain

/*

Your executables will try to find the addr2line tool, which is needed |
||||
to decrypt gcc debug information, enabling backtraces like this: |
||||
|
||||
0x0000000000403a7a: Hello at examples/backtrace.c:31 |
||||
0x0000000000403ac3: World at examples/backtrace.c:38 |
||||
0x0000000000401608: main at examples/backtrace.c:42 |
||||
0x0000000000401379: _start at libc/crt/crt.S:61 |
||||
|
||||
If that doesn't work, then your αcτµαlly pδrταblε εxεcµταblε will use |
||||
its own builtin fallback solution: |
||||
|
||||
0000ac2fa7e0 000000403a9b Hello+0x49 |
||||
0000ac2fa7f0 000000403ac4 World+0x22 |
||||
0000ac2fa800 000000401609 main+0x7 |
||||
0000ac2fa810 00000040137a _start+0x63 |
||||
|
||||
This is guaranteed to work if the .com.dbg file can be found. |
||||
Otherwise it'll print numbers: |
